The buffer size and the size passed to snprintf don't match, causing clang warnings. This patch increases a little bit the size of the buffer, and uses sizeof() to get the buffer size. This patch should be applied on top of the following patch: virtio: vdpa: new SolidNET DPU driver, by Alvaro Karsz alvaro.karsz@xxxxxxxxxxxxx Reported-by: Nathan Chancellor <nathan@xxxxxxxxxx> Signed-off-by: Alvaro Karsz <alvaro.karsz@xxxxxxxxxxxxx> --- drivers/vdpa/solidrun/snet_main.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/drivers/vdpa/solidrun/snet_main.c b/drivers/vdpa/solidrun/snet_main.c index d438a89b359..9ceacf96de0 100644 --- a/drivers/vdpa/solidrun/snet_main.c +++ b/drivers/vdpa/solidrun/snet_main.c @@ -540,7 +540,7 @@ static const struct vdpa_config_ops snet_config_ops = { static int psnet_open_pf_bar(struct pci_dev *pdev, struct psnet *psnet) { - char name[25]; + char name[50]; int ret, i, mask = 0; /* We don't know which BAR will be used to communicate.. * We will map every bar with len > 0. @@ -558,7 +558,7 @@ static int psnet_open_pf_bar(struct pci_dev *pdev, struct psnet *psnet) return -ENODEV; } - snprintf(name, SNET_NAME_SIZE, "psnet[%s]-bars", pci_name(pdev)); + snprintf(name, sizeof(name), "psnet[%s]-bars", pci_name(pdev)); ret = pcim_iomap_regions(pdev, mask, name); if (ret) { SNET_ERR(pdev, "Failed to request and map PCI BARs\n"); @@ -575,10 +575,10 @@ static int psnet_open_pf_bar(struct pci_dev *pdev, struct psnet *psnet) static int snet_open_vf_bar(struct pci_dev *pdev, struct snet *snet) { - char name[20]; + char name[50]; int ret; - snprintf(name, SNET_NAME_SIZE, "snet[%s]-bar", pci_name(pdev)); + snprintf(name, sizeof(name), "snet[%s]-bar", pci_name(pdev)); /* Request and map BAR */ ret = pcim_iomap_regions(pdev, BIT(snet->psnet->cfg.vf_bar), name); if (ret) { -- 2.32.0 _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
